DETAILED DESCRIPTION

The current methods and systems that compensate for noise interference and act to enhance mobile sound producing device use are limited and not always useful. Noise canceling headphones are a passive means for compensating for the noise interference surrounding a user during mobile music device use. However, noise canceling headphones are not useful for other mobile devices such as cell phones and other devices that are expected to be used without headphones. In addition, noise canceling headphones only reduce interference noise to a certain extent, reducing but not minimizing the level of noise interference. Cell phones, PDAs, and beepers may have primitive functions that enable the user to vary volume settings, which allow the user to raise the volume manually, to reduce noise interference when they are in a noisy setting. However, this manual volume adjustment function is not always efficient and can often be a cumbersome due to the requirement of manual adjustment of the volume levels. Therefore, there is a need for a system and method that automatically modulates the volume of mobile devices to minimize noise interference from a user's surroundings.

Embodiments of the invention provide a system and method for regulating the volume and frequency content of audio output devices based on the interference present in their aural surroundings. The invention maximizes the ability for people to use mobile devices like cellular phones, portable music players, and other devices that transmit auditory signals to alert, entertain, or inform the user. The system relies on a central server that transmits and receives signals from mobile devices and other noise-making objects (NMO) in a given area.

An example application of embodiments of the invention includes a cell phone user who may fail to hear their phone's alert when walking past a lawnmower or other NMO. In this example situation the lawnmower or NMO sends a signal to a server or user's mobile device to temporarily increase the volume on the phone until the noise no longer interferes with the user's ability to hear their phone's alert. When the NMO is no longer in the immediate aural surroundings of the user, or ceases operation, the server or mobile device reduces the volume back to its original level. The same set of actions can be applied to many scenarios with various mobile devices (PDAs, MP3 players, CD players, cameras, beepers, etc.) and NMOs (cars, trucks, household appliances such as vacuum cleaners, helicopters, stereos, etc.) Embodiments of the invention may also be applied to non-cellular or non-mobile sound devices, such as a home TV adapting its audio output when an airplane is flying above a house, or a car radio adapting its volume to a passing vehicle. The user has the ability to configure the device using a training module that adjusts the volume levels according to his or her preferred aural abilities.

In addition to audio volume level adjustments, embodiments of the invention may make other kinds of changes in device output sound to adapt to conditions in the aural surroundings, such as modifying sounds themselves in certain frequency bands to mask noise more efficiently. Embodiments of the invention may also be applied to recording devices used in noisy environments. Recordings made in noisy environments may have their audio characteristics adjusted accordingly to mask noise. Embodiments of the invention employ a noise manager to determine the effect of noise on sound production quality and to reduce interference of noise with the audio generated by the sound generating device.

Embodiments of the invention offer improved noise cancellation through the identification of the noise source (NMO). Noise cancellation techniques are inherently less accurate when the noise cancellation system itself is required to evaluate the source of the noise (e.g., music, speech, appliances, automobiles). In order to more efficiently cancel different kinds of noises there is a need to define their type. In addition, during the time required for conventional noise cancellation devices to evaluate the source of the noise, users may be exposed to loud or bothersome sounds before a response by the noise cancellation device is implemented. In embodiments of the invention, the NMO in the system that generates the noise sends a signal in advance to the noise cancellation device on what kind of noise it generates. The noise cancellation device, of embodiments of the invention, may then immediately choose specific noise cancellation models to reduce expected noise based on the signal received from the NMO. By sending information about expected noise type in advance, the NMO helps to prevent undesirable noise effects.

The noise cancellation devices of the present invention utilize radio signals traveling at the speed of light, which are approximately 240 times greater than the speed of sound. The large differential between the speeds of light and sound provide a relatively large anticipation interval for the noise cancellation of sounds originating from NMOs that are at a great distance from the noise cancellation devices of embodiments of the invention. The anticipation interval affect is especially pronounced for NMOs such as airplanes. Embodiments of the invention may include noise cancellation devices in homes that are within the flight paths of nearby airports that utilize radio frequency (RF) signals from airplanes, flying overhead to alter the audio output of sound devices in the home.

FIGS. 1A and 1B are block diagrams of exemplary systems of embodiments of the invention. System 100A of FIG. 1A is an example embodiment of a NMO in the form of a vacuum cleaner 102 that is equipped with a sound control device 104. The sound control device 104 has electronic logic processing, storage, and communication capabilities. The sound control device 104 may also have position determination devices. The position determination devices may utilize global positioning satellites (GPS) or proximity sensors. The NMO's 102 sound control device 104 communicates with a noise management server 106, and audio producing devices (108, 110, 112, 114), including but not limited to recording devices 108, televisions 110, telephones 112, and cell phones 116. The audio producing devices (108, 110, 112, 114) are also equipped with sound control devices 104 to facilitate communication, command and control with the NMO 102.

The noise management server 106 determines the proximity of the NMO 102 to the audio producing devices (108, 110, 112, 114) based on positional information from the sound control devices 104. If the noise management server 106 determines the NMO 102 is sufficiently close to produce noise interference with the audio producing devices (108, 110, 112, 114), the noise management server 106 commands the NMO 102 to signal the audio producing devices (108, 110, 112, 114) to increase their volume or alter their audio spectral content while the NMO 102 is in a given distance. The noise management server 106 determines the effect of the noise from the NMO 102 on the sound quality of the audio producing devices (108, 110, 112, 114), and acts to reduce the interference between the NMO 102 and audio producing devices (108, 110, 112, 114). In embodiments of the invention the noise management server may be integrated with the sound control device 104 on the NMO 102, or separated so as to communicate with additional NMO 102. Alternative methods for noise reduction and compensation include but are not limited to those described in U.S. Pat. No. 3,700,812 entitled “Audio System with means for Reducing Noise Effects”, U.S. Pat. No. 6,438,513 entitled “Process for Searching for a Noise Model in Noisy Audio Signals”, and U.S. Pat. No. 7,254,536 entitled “Method of Noise Reduction using Correction and Scaling Vectors with Partitioning of the Acoustic Space in the Domain of Noisy Speech” that are hereby incorporated by reference herein. There is constant interaction between the NMO 102 and the noise management server 106.

System 100B of FIG. 1B is an example embodiment of a NMO in the form of a vehicle A 118 that is equipped with a sound control device 104 that is in the vicinity of a second vehicle B 124. Vehicle B 124 is also equipped with a sound control device 104 for use with an on board radio 126 and the driver's cell phone 128. In addition, a pedestrian with a cell phone 130 is also part of this exemplary system 100B. As in the case of system 100A of FIG. 1, noise management server 122 determines the proximity of the NMO Vehicle A 118 to the audio producing devices (126 and 128) in vehicle B 124 and pedestrian cell phone 130 based on positional information from the sound control devices 104. In addition, the relative velocity (speed and direction) of the NMO Vehicle A 118 may also be tracked. If the noise management server 106 determines the NMO 118 is sufficiently close to produce noise interference with the audio producing devices (126, 128, 130), the noise management server 106 commands the NMO 118 to signal the audio producing devices (126, 128, 130) to increase their volume or alter their audio spectral content while the NMO 118 is in a given distance. The noise management server 106 determines the effect of the noise from the NMO 118 on the sound quality of the audio producing devices (126, 128, 130), and acts to reduce the interference between the NMO 118 and audio producing devices (126, 128, 130).

The radio 126 contains an auditory profile of the acoustic environment within vehicle B 124. The acoustic environment includes, for example, the volume of the voices of passengers, the sound volume of wind if vehicle B has windows that are open or closed, the sounds of moving parts within the car, etc. When the radio 126 receives a location and characteristic noise signal from an approaching vehicle A 118, the radio 126 may calculate the volume and frequency adjustments required to maintain consistent audio quality. The driver's cell phone 128 employs additional features of sound control device 104 to maintain sound quality not only for the user, but also for the individual who is calling the cell phone 128. The cell phone 128 has its volume and sound quality adjusted accordingly to the acoustic environment. In addition, sound is modified and delivered to the user on the receiving end of the phone such that interference from the driver's environment is removed and the sound quality is maintained.

FIGS. 2A and 2B are example embodiments of the invention involving hearing aid devices 202. In FIG. 2A, when vacuum cleaner 200 approaches hearing aid device 202, a noise characteristic signal is sent to the hearing aid device 202, indicating the location and character of the noise from the vacuum cleaner. Hearing aid device 202 contains an auditory profile of its surroundings. For example, the hearing aid device 202 may differentiate between sounds in a large room versus sounds in small room. Sounds in a small room are received at relatively equal volume throughout the room as compared to a large room, where different points in the room receive different volume levels from a single sound source. The hearing aid device 202 may calculate the acoustic impact of the noise of the vacuum cleaner 200 or other NMO based on the location of the vacuum cleaner (NMO) 200 and the noise characteristic data that the vacuum cleaner 200 sends to the hearing aid device 202. Using the information provided by the vacuum cleaner (NMO) 200, the hearing aid device modulates the amplitude and frequency of the sound it emits to compensate for any interference caused by the vacuum cleaner (NMO) 200.

FIG. 2B emphasizes the link between the hearing aid device 202 and a sound adjusting service 204. The sound adjusting service 204 may be remote, and serves to modify the sound emitted by the hearing aid device 202 according to the characteristic noise signal of the environment surrounding the hearing aid device 202. The sound adjusting service 204 may modify the audio emitted by the hearing aid device 202 via two methods. In the first method, the sound adjusting service 204 sends an exact algorithm of how the audio characteristics are changed within the hearing aid device 202. In the second method, the sound adjusting service 204 modifies the sound to be emitted by the hearing aid device 202, and sends a digital recording of the audio to be emitted by the hearing device. The audio that the sound adjusting service 204 sends to the hearing device is integrated with the sounds emitted by the hearing aid device 202.

FIG. 3 is a block diagram of an exemplary method for how the adjusting service 204 of FIG. 2B creates an algorithm to send to the hearing aid device 202. In the method, audio frequency bands received by the user that require adjustment are identified (block 300). The audio characteristics (noise level) of the individual sound frequency bands are identified (block 302). The necessary audio quality (audio level) for the given sound (frequency band is identified (Block 304). The data that characterizes the necessary audio quality is used to re-map the audio quality of the existing sound (306).

FIG. 4 illustrates a flowchart for implementing embodiments of the invention. The process starts (block 400) with a determination of whether a NMO is producing noise near (audible range) a noise sensitive device (decision block 402). If there are no NMO near the noise sensitive device (decision block 402 is NO) and the sound is produced by the noise sensitive device unaltered (block 418). However, if there is an NMO near a noise sensitive device (decision block 402 is YES) and the NMO is aware of its noise characteristics (decision block 404 is Yes), the NMO sends noise characteristics to the noise sensitive device (block 406). If the distance between the NMO and the noise sensitive device is known (decision block 410 is YES), an estimated re-map is based on noise characteristics from the NMO that is also adjusted for the distance between them (block 416). A re-map of the audio in the noise sensitive device is made (block 414), and sound is produced (block 418) and the process ends (block 420). If the distance between the NMO and the noise sensitive device is not known (decision block 410 is NO), an estimated re-map is based on noise characteristics from the NMO alone (block 412). If the NMO is not aware of its noise characteristics (decision block 404 is NO), the re-mapping algorithm is estimated from the actual noise from the NMO (block 408), and the audio in the noise sensitive device is re-mapped (block 414). After the audio is re-mapped, the noise sensitive device reproduces the sound (block 418) and the process ends (block 420).

The data exchange system of the present invention may reside on a stand-alone computer system, which may have access to the Internet, or may reside on a computer system, which is part of the network through which there is Internet access. With a connection to a network and/or the Internet, there are several different ways in which the process software used to implement the systems and methods of the present invention may be integrated with the network, and deployed using a local network, a remote network, an e-mail system, and/or a virtual private network. The following descriptions review the various ways of accomplishing these activities.

Integration of Data Exchange System Software.

To implement the data exchange systems and methods of the present invention, process software, which is composed of the software as described above and related components including any needed data structures, is written and then if desired, integrated into a client, server, and network environment. Taking those steps needed to enable the process software to coexist with other application, operating system and network operating system software and then installing the process software on the clients and servers in the environment where the process software will function accomplish this integration. An overview of this integration activity will now be provided, followed by a more detailed description of the same with reference to the flowchart of FIG. 5.

The first step in the integration activity is to identify any software on the clients and servers where the process software will be deployed that are required by the process software or that need to work in conjunction with the process software. This includes the network operating system, which is the software that enhances a basic operating system by adding networking features.

Next, the software applications and version numbers are identified and compared to the list of software applications and version numbers that have been tested to work with the process software. Those software applications that are missing or that do not match the correct version are upgraded with the correct version numbers. Program instructions that pass parameters from the process software to the software applications will be checked to ensure the parameter lists match the parameter lists required by the process software. Conversely, parameters passed by the software applications to the process software will be checked to ensure the parameters match the parameters required by the process software. The client and server operating systems including the network operating systems are identified and compared to the list of operating systems, version numbers, and network software that have been tested to work with the process software. Those operating systems, version numbers, and network software that do not match the list of tested operating systems and version numbers are then upgraded on the clients and servers to the required level.

After ensuring that the software resident on the computer systems where the process software is to be deployed is at the correct version level(s), that is, has been tested to work with the process software, the integration is completed. Installing the process software on the clients and servers does this. Armed with the foregoing overview of the integration activity, the following detailed description of the same should be readily understood.

Referring to FIG. 5, step 500 begins the integration of the process software for implementing the search and reference systems and methods of the present invention. It is determined whether there are any process software programs that will execute on a server or servers at step 502. If this is not the case, then integration proceeds to determine if the process software will execute on clients at step 514. If there are process software programs that will execute on a server(s), then the server addresses are identified at step 504. The servers are checked to see if they contain software that includes the operating system (OS), applications, and network operating systems (NOS), together with their version numbers, that have been tested with the process software at step 506. The servers are also checked to determine if there is any missing software that is required by the process software as part of the activity at step 506. A determination is made whether the version numbers match the version numbers of OS, applications and NOS that have been tested with the process software at step 508. If all of the versions match, and there is no missing required software, the integration continues at step 514. If one or more of the version numbers do not match, then the unmatched versions are updated on the server or servers with the correct versions at step 510. Additionally, if there is missing required software, then it is updated on the server or servers at step 510. Installing the process software at step 512 completes the server integration.

Step 514, which follows either step 502, 508 or 512, determines if there are any programs of the process software that will execute on the clients. If no process software programs execute on the clients, the integration proceeds to step 520 and exits. If there are process software programs that will execute on clients, the client addresses are identified at step 516.

At step 518, the clients are checked to see if they contain software that includes the operating system (OS), applications, and network operating systems (NOS) software, together with their version numbers, that have been tested with the process software. The clients are also checked at step 518 to determine if there is any missing software that is required by the process software.

At step 522, a determination is made if the version numbers match the version numbers of OS, applications and NOS that have been tested with the process software. If all of the versions match, and there is no missing required software, then the integration proceeds to step 520 and exits.

If one or more of the version numbers do not match, then the unmatched versions are updated on the clients with the correct versions at step 524. In addition, if there is missing required software, then it is updated on the clients as part of step 524. Installing the process software on the clients at step 526 completes the client integration. The integration proceeds to step 520 and exits.
